is this enough support to prevent slab bulging?
Editied for clarity.
Hi, we are pouring a floating slab in zone 4a for our shop.
Do I have enough kickers to prevent bulging for my slab?
1-1/2″x 12″ actual dimension pine form board.
2×4 waler? below form top edge.
Kickers every 4ft.
I will also place about 5″ of the soil used for pad along bottom edge of form board.
At the 8ft O.C. concrete piers I used a single 3″ Tapcon to hold form board height while I did the real supports.
2″ recycled 25psi XPS (2 pieces of 1″).
